Rootstock offers three integration paths for dApps. Pick the one that matches the problem your users have:

- **RIF Relay:** Your users hold tokens but no rBTC for gas. RIF Relay lets them pay fees in tokens, or lets your dApp sponsor the fees.
- **rBTC Flyover:** Your users need rBTC from BTC without the PowPeg wait of about 17 hours. A Liquidity Provider advances the funds in 20 to 60 minutes.
- **RNS:** Your users struggle with long hex addresses. RNS resolves names such as `alice.rsk` to addresses.
